I dont know uf it's cold or not I have never been theta, but what I can't understand is you know how we have day from the sun? How come space does not have day? It looks black, like a black sky. But why?

I reckon space is cold as it has no atmosphere. Even near the sun it may be cold.Its just the earth and other similar planets have an atmosphere and the cosmic rays are able to transfer heat through these particles.

As altitude increases from the earth the temp drops...as does the atmosphere particles

You'd think the higher up you go from land (closer to the sun) the warmer it would get. Just the opposite

it's cold because stuff has to rub together in orderto make heat, and in outer space (apart from some rocks andpebbles, here and there, floating around) all of the atomsfloating around are about 1 cm. apart from one another.

How about the moon as an example, it doesn't have an atmosphere (supposedly).

How hot and cold does it get on the moon?

As you may have learned, the moon doesn't have any air around it. The air that surrounds our earth acts as a nice blanket to keep us warm and comfy! But the moon, since it doesn't have this blanket, gets much colder than the earth — and much hotter than the earth. On the side of the moon that the sun is shining on, the temperature reaches 260°Fahrenheit! That is hotter than boiling. On the dark side of the moon, it gets very cold, -280° Fahrenheit.

space is neither hot or cold, it has no temperature cos it's void. There is no heat conduction or convection, only radiation.

But the truth is, you could jump the ship in space, even butt naked from one capsule to another, maybe 30 feet apart without ill effects ... you will radiate some warmth off but you then just drink hot chocolate afterwards

Complete non-sense, ice meteors have passed almost directly through the sun and made it out of the other side. Even 1,000 degrees C and it wouldn't make it, but more than one has that we've been able to see.

Thank you.Finally a poster, who knows and understands physics.

There is no effing "cold" in space.

Cold and heat are the function of vibration of atoms/molecules. In vacuum (space) there is neither - therefore NO heat or cold. The only heat is possible by the sun's RADIATED heat hitting a solid (or semi-solid) object and IT's molecules heating up.

The biggest problem in space is the getting rid of heat. Radiation is not particularly efficient, and convection is non-existent.(Principle of the vacuum bottle's heat retainage function)

Oh, like you were there when THAT happened. Right. I call SHENANIGANS!!!
